VWR Plate Gl .75MM Spacers PK2. The precision-machined stainless steel spacers eliminate the need for special deep or wide openings. The top opening is designed for visual inspection and insertion of filters or hoses without influencing the volume or pressure in the sample. An O-ring-sealed stainless steel hemisphere provides nearly a rimless system with no overhang or overpipes. Supplied with a hex drive on one end and a ball-valve on the other end to prevent back-flashing and leakage in the event of a power failure. The spacers are supplied in pairs and storage is through those holes in the base.
